Oliver Geiss focuses his practice on competition and foreign direct investment (FDI) laws in the European Union and Germany. He is a member of the firm’s Global Board and actively supports its DEI initiatives in a leading role.

Oliver regularly advises clients from all around the globe on merger control and FDI notifications of cross-border transactions worldwide. He has extensive experience in a variety of industry sectors, including chemicals, automotive, energy and pharmaceuticals.

Comments in directories like The Legal 500 highlight the added value Oliver brings to transactions (“thanks to his contributions, we were able to complete a very challenging project on time”), and state that they “would recommend him to anyone” and elicit praise for his expertise and responsiveness over different time zones.

He has also represented companies in some of the largest cartel investigations before the European Court of Justice, the European Commission and the German Federal Cartel Office, including air freight, LCD screen, optical disc drives, refrigeration compressors and industrial batteries, as well as in civil damage actions before national courts. Oliver is at the forefront of developments and regularly publishes in this area.

He frequently advises clients on EU state aid law and competition aspects of commercial agreements, such as distribution agreements or joint buying or selling arrangements, the EU public procurement rules, and general EU law aspects such as the fundamental freedom. Oliver regularly appears before the European Court of Justice; for instance, on state aid matters or, recently, a major data protection matter before the Grand Chamber of the Court of Justice of the European Union (CJEU).
